The short answer: email marketing interviews test strategy (who gets what, when, and why), automation (welcome, abandoned-cart and re-engagement flows), testing and metrics (beyond open rates), deliverability (authentication, list hygiene, spam complaints) and compliance. Bring two or three campaigns with numbers, know why open rates are less reliable than they used to be, and be ready to critique one of the company’s own emails. Deliverability knowledge sets candidates apart: Gmail, for example, requires bulk senders to authenticate with SPF, DKIM and DMARC, support one-click unsubscribe, and keep reported spam rates below 0.3%.
Sample answers are illustrations, not quotes from real candidates.
Strategy questions
“How would you build an email program for us?”
“I’d start with the business goals (for example, first purchases and repeat purchases) and the customer lifecycle. Then I’d map the key moments: welcome, first purchase, post-purchase, replenishment, win-back. Automated flows cover those moments, and campaigns cover launches and promotions. I’d segment by behavior and value, set a testing plan, and report on revenue and retention, not just opens.”
“How do you segment a list?”
By behavior (purchases, browsing, engagement), lifecycle stage (new, active, lapsed), value (high and low spenders), and declared preferences. Start with a few segments that would change the message, rather than many that don’t.
“How often should we email?”
There’s no universal answer: test frequency by segment, watch unsubscribes and spam complaints alongside revenue, and let highly engaged subscribers receive more than inactive ones.
Automation questions
- “Which flows would you set up first?” Welcome series, abandoned cart or browse, post-purchase, and re-engagement, because they reach people at moments of high intent.
- “Walk me through a welcome series.” Email 1 immediately: thanks, what to expect, and the offer if one was promised. Email 2: the brand story or best sellers. Email 3: social proof or a guide. Then move non-buyers to a different path from buyers.
- “How do you handle inactive subscribers?” A re-engagement series, then suppress those who don’t respond, which protects deliverability.
Testing and metrics questions
“Which metrics matter most?”
“Revenue and conversions per email (or per recipient), click-through rate, unsubscribe and spam complaint rates, and list growth. Open rates are less reliable than they used to be because some email apps load images automatically, which can count as opens, so I treat them as a rough signal.”
“How do you run an A/B test?”
One variable at a time (subject line, offer, layout, send time), a sample large enough to detect a meaningful difference, a primary metric decided in advance (usually clicks or conversions), and a written result so the team learns from it.
“A campaign underperformed. What do you do?”
Check the basics (deliverability, rendering, links), compare against benchmarks for that segment, then look at the offer, audience and timing before changing creative.
Deliverability questions
- “What are SPF, DKIM and DMARC?” Email authentication standards that prove you’re allowed to send from your domain and that messages weren’t altered. Google’s sender guidelines require all senders to Gmail to set up SPF or DKIM, and those sending more than 5,000 messages a day to Gmail to set up SPF, DKIM and DMARC.
- “What else do mailbox providers look at?” Spam complaints (Google asks senders to keep reported spam rates below 0.3%), bounces, engagement, and list quality. Marketing messages to Gmail must support one-click unsubscribe and include a visible unsubscribe link.
- “Our emails are going to spam. What do you check?” Authentication, recent complaint and bounce rates, sudden volume changes, list sources (bought lists are a common cause), and content or links flagged by filters.
Compliance questions
“What does CAN-SPAM require?”
The U.S. Federal Trade Commission’s compliance guide summarizes the main rules: accurate header information, no deceptive subject lines, identifying the message as an ad, including your valid physical postal address, a clear way to opt out, and honoring opt-outs within 10 business days. Each violating email can bring penalties of up to $53,088. Other countries, such as those in the EU, have stricter consent rules, so check where your subscribers are.
Practical tasks you may get
- Critique our latest email: subject line, preheader, offer, layout, call to action, mobile rendering.
- Plan a welcome series or a re-engagement flow.
- Write two subject lines to test against each other, with your hypothesis.
- Analyze campaign results from a small dataset.
Questions to ask the interviewer
- “Which email platform do you use, and who owns deliverability?”
- “What share of email revenue comes from automated flows versus campaigns?”
- “How do email and other channels work together here?”
